PUMPING APPARATUS.

Specification of Letters Patent.

Patented Oct. 22,1912.

Application filed July 5, 1910. Serial No. 570,391.

To @ZZ whom it 'may concern:

Be it known that I, HASCAL A. Hoem'., a citizen of the United States,residing at Boston, in the county of Suffolk and State of Massachusetts,have invented certain new and useful Improvements in Pumping Apparatus;and do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My present invention relates to improvements in pumping aparatus, and isespecially intended to provide a pump automatically operated bycompressed air, which is adapted to force water, oil, or other liquid,to a considerable height.

The apparatus contained in my invention comprises one or more pairs ofcylinders to which the compressed air and water are alternatelyadmitted, and from which the air or water is alternately expelled by theautomatic apparatus vherein described and claimed.

Reference is had to the accompanying drawings, in which the same partsare indicated by the same letters throughout the several views.

Figure l is a front view showing one of the cylinders in elevation, andone in section, parts being broken away. Fig. 2 is a sectional elevationtaken between the tw'o cylinders of Fig. l and looking to the right,with the apparatus for automatically turning on or off the air pressureand for carrying away the water shown in elevation. Fig. 3 shows ahorizontal view of a four way cock and its casing, used for turning onand oif the air pressure. Fig. 4 shows a section through the Fig. 3along the line L -l of said ligure. Fig. 5 is a detail showing insection and in plan the four way cock of Fig. 3.

A and A are tw'o cylinders having closed upper heads a perforated as ata@ to receive the end of the air pipe B, which air pipe is connected bythe pipes C and C (see Fig. 2) to any suitable source of supply ofcompressed air.

C3 is an exhaust pipe, which to prevent leakage may be closed by a valvec3. Connecting the pipe C with the pipe B is a four way cock E, shown indetail in Figs. 3 to 5, whose casing F is connected at opposite sides tothe pipes B and the pipes C and C3 respectively. This four way cock ispreferably made tapered as shown, having its seat grooved as at e0 toengage balls c supported by the block E pressed outward by the spring'c, and thus the four way cock is automatically adjusted for wear. Thefour way cock is provided with an arm G, having a pin g projectingtherefrom, as shown in Figs. l and 2, and this pin projects in the pathsof the two arms H and H of the tumbling bob. These arms H and H are heldin the Y shaped socket H2, pivoted as at h2, and the said socket alsocarries an arm H3 carrying an adjustable weight Ht.

I is the frame forming the support for the pivot of the tumbling bob,which frame may be conveniently attached to the tops of the twocylinders, and thus serve to brace the same.

The cylinders A and A are mounted on suitable supports, such as K, andhave their bottoms perforated as at L to permit the iniux of water fromthe pipe M connected by the water main Vi to any suitable water supply.Check valves opening inward are provided in said water main, as at M2(see Fig. 2). The water is carried off by the pipes N past the checkvalves, opening outward, N2 (see Fig. 2) and into the delivery pipe N.

O is a small pipe for compressed air, which opens at intervals, as at 0,into the delivery pipe N, to facilitate the pumping, as will behereinafter described.

Each cylinder may be provided with a suitable manhole and a manholecover F for securing access to the interior thereof when desired. Eachcylinder is provided with a box Q. for the pivot of the float, and tobrace the two cylinders these two boxes may be bolted together, as shownat Q in Fig. l.

R and R represent two floats, each connected to an arm S secured to therock shaft S journaled in the box Q, these rock shafts S carryingoperating arms T and T respectively. Opposite these operating arms arecorresponding arms U carrying weights U', as shown in Figs. l and 2.These operating arms T and T have lugs t and t to engage the arms H andH respectively, the arm H being bent outward as at 7L (see Fig. 2) toclear the arm T but to engage the lug` t on the arm T. It will be seenthat the arms S, T and U and S, T and U respectively, rocking about thepivots S, constiutute F-shaped rocking frames,

having the upper arm engaging the tumblel bob and that the parts arebalanced by the weights U. The two arms H and H are provided with pins71, and 7L to engage the arms T and T respectively.

The operation of the apparatus is as follows: In the position shown inFig. l the cylinder A is full of water, and air pressure from the fourway cock E is turned on to cylinder A and cut off from A which is thenconnected to exhaust C3. As water is blown out of cylinder A under airpressure, it is rising in cylinder A under hydraulic pressure, liftingfloat R and causing arm T to engage pin h. and press arm H back, liftingweight H4. lWhen the float R rises far enough to carry weighted arm H3beyond the vertical position, the weight H4 will rock arm H into violentcontact with pin g, which will rock the arm G in the opposite direction,cutting off air from cylinder A and opening exhaust, and turning airpressure on to cylinder A. It will be seen that the arm T acting as ashort lever, will engage the pin L near the end or the arm H at thebeginning of the act of swinging' the weight I-ll4 toward the verticalposition, and that at this time the weight U will also tend to assistthe float R in lifting said weight H, thus giving increased leverage andthe help of the weight U to start said weight H4 upward, but as thefloat R rises bringing the weight H4 toward the vertical position thelug T at the end of arm T will engage the arm H, nearer its pivot thanthe pin It, and the pin L will swing clear of engagement with the arm T,causing a quicker movement of said arm H, and of the weight H4, but at aless leverage, while the weight U will partially oppose the upwardpressure of the water on theA float; the general result being that theweight H4 is started slowly with great leverage, is swung more rapidlyas it approaches the vertical position, and when it passes the verticalposition and swings away from engagement with the arm T the weightchecks the float from swinging up too rapidly, due to the release ofpressure on the arm T. Water will now rise' in A and will fall in A. Itwill be understood that while the water is rising in cylinder A it isbeing pressed out of cylinder A by the compressed air, and that when thefloat R in cylinder A has risen enough to operate the tumbling bob, theioat R in cylinder A has fallen to its lowest position, swinging the armT back and causing it to engage the pin h as the water rises again incylinder A. The rising of the float R will rock the tumbling bob in theopposite direction, until, when the float R is high enough, the weightH4E will again take charge of the tumbling bob and throw the parts backto the initial position shown in Fig. l. The cycle of operations iscontinued automatically for an indefinite period, so long as theapparatus is kept in repair, and so long as the supplies of compressedair and water are maintained.

By blowing compressed air through the pipe O and inlets o into the waterdeliver7 pipe N, the operation of pumping is facilitated, as fullyexplained in my application, filed Jan. 9, 1909, Serial No. 471,472, andentitled, Improvements in compressed air water elevators.

It will be obvious that various modifications might be made in theherein described apparatus, and in the combination and arrangement ofparts which might be used without departing from the spirit of myinvention.
